Types of Barcodes Explained: 1D vs 2D QR Codes, NFC, RFID & More.

Discover the complete world of barcodes in this ultimate guide! From classic 1D barcodes like UPC, EAN, and Code 128 that revolutionized retail in the 1970s, to powerful 2D codes like QR codes, Data Matrix, PDF417, Aztec, and MaxiCode – we break down how they work, their superpowers (error correction, massive data storage), and where they're used today. We also cover '3D' barcodes (engraved/depth-based for harsh environments), plus contactless tech: NFC tags for taps (payments, pairing), RFID for tracking, and even Apple App Clip Codes.
